Application filed -September To all whom it may concern:

Be it known thatLIsAAo PLosT, a citizen of the United States, residingat the city of St. Louis and State of Missouri, have invented a new anduseful Rail Tie, of which the following is a specification.

This invention relates to improvements in rail ties, and consists in thenovel construction hereinafter disclosed.

An object of the invention is to provide a metallic-"rail'tieconstructed to withstand a maximum crushing pressure and having asufficient resiliency to compensate "for rail vibration.

-Another object of the invention is to provide a rail tie with novel andefficient means for connecting therail'i'ntrue alinement to Fig. 1 is aplan view of a section of rail and a section of the tie embodying theinvention.

Fig. 2 is a front elevation of a portion of the rail tie showing therail in connection therewith in cross section.

Fig. 3 is an end view of the rail tie.

In the embodiment of the invention illustrated in the drawing, the maincross memher 1 of the rail tie is shown as comprising a metallic membersemi-circular in cross section, arranged to form an arched supportingwall. The member 1 is preferably made by cutting a cylindrical boilertube or similar tube longitudinally on a median-line.

In order to form a receiving recess for the rail, the member 1 isflattened, as illustrated in Fig. 2, said recess being indicated by 2.It will be understood that the recess 2 is formed adjacent to each endof the cross member 1, being sufficient for illustrative purposes,however, to show only an end section of the main cross member.

The recess 2 extends transversely of the rail member 1 and has a bottomhorizontal wall for supporting the bottom face of the lower flange 8 ofthe rail 4. The recess 2 is of a width corresponding to the crosssectional width of the flange 3 and is of suflicient depth so that thenarrow extremities of the beveled faces 5 of the lower flangeSpecification of Letters Patent.

. of the rail will be below the plane of the 'top of the recess.

In orderto reinforce 'the'm'ember l ben'eath the point of 'strainan'd toprevent the spreading of the semi-circular member 1,"a plate 6 havingmarginal up turn'ed flanges 7 isprovided. The plate (Sis Of a width sothat the flanges 7"over"-lie the si deedges of the wall of the member 1,constituting a brace or strut holding the tie member 1 from spreading.

Adjacent to eachend of the plate 6 and "formed by upwardly deflectingwalls oftlie plate are recesses S-adapte'd to receive and hold fromturning the heads 9'of bolts 10. Preferably'th'e'walls of the platesurround ingfthe heads 9 of the bolts are-erim edinwardly to rigidlyembrace the heads 9 "of the bolts and prevent the bolts from turning.The bolts 10 extend upwardly and are of a length sufficient to riseabove the top wall of the member 1, passing through openings formedtherein for that purpose.

Adjacent to and extending longitudinally from the side walls of therecesses 2 are flattened portions 11 adapted to constitute seats forclamps 12, said clamps 12 having their inner ends 13 deflected upwardlyso that they rest against the inclined upper walls of the flange 5 ofthe rails.

In connecting the rails with the ties, the clamp 12 on one side ismounted on the bolt 10 and a nut 14 for the bolt screwed in place toadjust and retain the clamp 12. The rail is then slipped in place in therecess 2, the side wall of'the flange 5 of the rail extending under theadjusted clamp. The clamp 12 on the opposite side is then mounted inplace over the corresponding bolt and the nut 14 of the bolt screweddown in place.

In track laying, inasmuch as the recesses 2 are all in alinement byalining the ends of the ties, an alined rail receiving seat formed bythe recesses 2 is provided so as to insure ber, bolts supported by saidplate and extending through the top Wall of said firstnamed member, andclamps adapted to be adjusted on said bolts for clamping the rail inconnection With said first-named member.

2. A rail tie, comprising a semi-cylindrical member having a transverserail receiving recess in the top thereof, and rests extending laterallyfrom said first-named recess; a plate having side flanges adapted to bemounted beneath said recess, said side flanges constituting abutmentsfor the bottom edges of said first-named member, said plate beingprovided With recesses; bolts extending through said plate on eitherside of the recesses in said first-named member, said bolts projectingabove the top Wall of said first-named member; clamps carried by saidbolts; and nuts received by said bolts for clamping said clamps againstthe upper Wall of the lower flange of the rail for holding said rail inconnection With said firstnamed member in clamping engagement.

3. A rail tie, comprising an arched rnetallic cross member having a railreceiving recess, a retaining plate mounted at the bottom of'said crossmember having means thereon for preventing the lateral spreading of saidmember, clamping devices in connection with said cross member forclamping the rail in position in said recess, and elements engaging saidclamping devices and said plate and holding all of said-parts in properrelationship With each other and with the cross member.

'41. A rail tie, comprising a semi-cylindrical member having its edgesdownward and having a rail receiving recess in the top thereof, aretaining plate in connection with said member to preventthe member fromspreading, clamps on top of said member at the sides of the recess, andbolts passing up- Wardly through said plate and through the top of saidmember and through said clamps holding all of said parts in properrelationship with each other.
